Courting Disaster

My boyfriend of one-year, who is Brazilian, went to Brazil for three months for business and personal reasons. Before he went to Brazil, we had such a wonderful relationship, but I broke up with him right before he went away because I knew that he would be unfaithful. When he came back he told me that he slept with three different women and on several occasions, but that it was just sex and didn’t mean anything. Still, this has me really upset, even though he says he loves me. I just don’t know if he is worth it?
